T0 all zuwm, it 717.61.70/ concern:

Be it known that I, ANDERS E. NEIGLICK, a citizen of the United States,and a resident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Knives, of which thefollowing is declared to be a full, clear, and exact description.

The invention relates to knives of that type in which the blade may beincased Within a suitable handle, but which when in use is rigidlysecured in projected position within the end of the handle.

The improvement seeks to provide a simple and effective construction inwhich the knife-blade may be readily and quickly projected from thehandle and securely held in projected position and in which theknifeblade may be also easily drawn into the handle.

A further obj ect of the invention is to provide a simple inexpensivearrangement of operating parts which may be easily and quickly assembledwithin the knife-handle.

lith these objects in view the invention consists in the features ofconstruction, combinations, and arrangements of parts hereinafter setforth, illustrated in the accompanying drawings, and more particularlypointed out in the appended claims.

1n the drawings, Figure 1 is a side view of the improved knife with theparts incased within the handle. Fig. 2 is a similar view thereof,showing the knife-blade projected for use. Fig. 3 is a view similar toFig. 2, with the handle in section to show the operating parts. Fig. 4is a perspective view of the knife-blade and its operating parts shownseparated from one another to illustrate the manner in which they areassembled. Fig. 5 is a perspective view of the shell forming the tubularhandle. Fig. 6 is a perspective view of the sectional lining of thehandle provided with grooves in which the blade slides. Fig. 7 is aperspective view of the U-shaped releasing-slide. Fig. 8 is a sectionalview of the improved knife, showing the bladeand operating parts-incasedwithin the handle. Fig. 9 is a similar' view showing the blade projectedfrom the handle. Fig. 10 is a similar view showing the blade drawn intothe handle and the operating parts withdrawn therefrom. Fig. 1 1 is across-section on line 1 1 11 of Fig. S. Figs. 12 and 13 are views oftheopposite end pieces of the handle.

The knife-handle preferably comprises a tubular metal shell 10, asillustrated in Fig. 5, which is preferably of oval cross-section. Theend pieces 11 and 12, which are illustrated in Figs. 12 and 13, are setwithin the ends of the tube 10, and the metal of the latter is crimpedover the end pieces to hold them in place, as illustrated in Figs. 3 and8. The tubular handle 10 is preferably provided with a cover or grippingportion 10', of leather or suitable material, that terminates somewhatshort of its ends. The end piece 11 is provided with a cross-slot 13,through which the knife-blade 14 is arranged to roj ect. The knife-bladeis arrangedD to slidle in suitable guide grooves or ways within thehandle, and these grooves are preferably formed upon an inner liningthat comprises and bent to proper semi-oval shape to fit within thetubular shell 0r handle 10.l The mid-portion of each of the sections 15is shaped to form a suitable guide-groove 16, and the edges of thesesections have outwardly-projecting lugs 17, that set within openings 1Sin the tube or handle 10, so that the guide-grooves 16 are securely heldin proper relation opposite each other. The inner end of the steel blade14 is provided with an integral rectangular portion 19 of uniformthickness that sets snugly Within the guide-groove 16, so that the bladeis securely held against twisting.

The side edges of the squared portion 19 at the inner end of the bladeare provided with notches 20. A pair of U-shaped clips 21, which may beconveniently formed of sheetbrass cut and bent to proper form, set overthe side edges of the squared portion 19, and outwardly-projecting lugs22 on the outer faces of the clips engage the shoulders at the ends ofthe notches 20, (see Fig. 3,) so that the knife-blade is compelled tomove longitudinally with the clips 21.

The shifter for projecting the knife-blade the handle and to projecttherefrom, preferably throiwh an opening 23 (see Fig. 13) in lthe endpate 12. This shifter preferably comprises the sections 24, that arepreferaably formed of spring-steel. At its inner end the central portionof each section of the shifter is cut away to form a spring tongue orfinger 25. The upper or inner ends of the spring-tongue 25 are bentinwardly, as at 26. At its lower or outer endfthe central portion ofeach section 24 of the blade-shifter is cut separate sections 15, thatare of sheet metal IOO from the handle is arranged to 'slide within awayto form an outwardly-proj ecting springcatch 27, having a shoulder 28and a fingerpiece 29. The outer portions of the sections 24 are bentinwardly toward each other at their lower ends (see Figs. 3 and 4) andare provided with loops 30, extending about the pintles 31 of a loop orring 32. The bladeshifter is thus practically U-shaped, the separatesections thereof being connected together by the loop or ring 32.

The lower or inner edge of the squared portion 19 of the blade ispreferably cut away (see Fig. 4) to form a notch 33, and the ends 26 ofthe spring tongues or Jlingers 25 are arranged to project within thenotch and engage grooves 34 in the inner face thereof to project theknife-blade 14 and hold it in projected position. (See Fig. 9.) Theshoulders 28 of the spring-catches 27 are arranged to engage the innerface of the end plate 12 of the knife-handle (see Fi s. 8 and 9) andhold the blade-shifter loc ed in position within the handle. Theiinger-pieces 29 of the catches extend outward through the opening 23 ofthe plate 12 on opposite sides of the ring or loop 32, so that they maybe conveniently gripped to release the bladeshifter. It is obvious thatthe springtongues 25 and catches 27 could be formed separate from themain body of the bladeshifter; but, as stated, the latter is preferablyformed of spring metal, so that these parts may be formed integraltherewith, and thus occupy less space.

The U-shaped clips extend over the side edges of the sections 24 of theblade-shifter, (see Fi s. 3, 8, 9, and 10,) and the extreme inner. en sof the sections 24 of the shifter are rovided with outwardly-projectinglips or ugs 35, that are arranged to en age shoulders 36 on the upper orouter e ges of the clips 21, so that the knife may be drawn into thehandle by operating the shifter.

Suitable means are provided for releasing the spring 25 from the innerend of the blade 14, so that the blade and blade-shifter may i .be slidpast each other and both incased within the handle. This releasingdevice preferably comprises a U-shaped slide 37, constructed asillustrated in Fig. 7 and preferably formed of sheet-brass or othersuitable metal. This slide is arranged within the sections 24 oftheblade-shifter and is provided at its upper end with outwardly-projectinglips or lugs 38, that are arran ed to engage shoulders or lugs 39 on thec 'ps 21. (See Figs. 3 and 4.) v The slide 37 is also provided adjacentits inner end with openings 40, through which the ends 26 of thespringtongue 25 are arranged vto project into engagement with theknife-blade. The outer or lower end of the slide 37 has its centralportion cut away to form a notch 41, through which the shoulders 28 ofthe springs 27 are arranged to project. The lower connecting portionbetween the sides of the slide are provided with lugs 42, projectinginwardly and normally in line, (see Figs. 3 and 4) with notches 43 onthe side edges of the finger-pieces 29 of the spring-catches 27 Inassemblin theVparts the lining-sections 15 may be readi y set within thetubular handle 10 and the lugs 17 of the sections interlocked with theopenings 18 of the tubular handle. The end plate 11 may then be setwithin one end of the handle, the blade is placed between the sides ofthe U-shaped slide 37, and the latter is arranged between the sections24 vof the U-shaped bladeshifter. The clips 21 are then set over theside edges of the blade-shifter and slide with the lugs 22 thereofengaging the ends of the notches 20 in the inner end of the knifeblade.The operating parts thus assembled may be set within the handle, withthe side edges of the squared portion 19 of the knifeblade engaging theuide-grooves'l, and the lower or outer capate 12 may be then fixed inplace.

In the normal inoperative osition of the knife (shown in Fig. 8) bothglie knife-blade and the operating parts are incased within the handle.To prevent the blade from dropping out, one of the lugs 22 on one of theclips 21 is bent upwardly and outwardly to form a Spring-catch 44, (seeFig. 4,) that is arranged to engage a groove 45 (see Fig. 3) at thelower or outer end of one of the guide-channels 16. When the knife isdrawn into the casing, the edge of the spring-catch 44 will engage thegroove 45 an prevent the knife from dropping out. In this position alsothe flanges or lips 38 (see Fig. 8) on the slide 37 abut against the endlate 11, the projections or lips 35 on the b ade-shifter sections 24abut against the lips or flanges 38, and the slide and blade-shifter aresnugly held in position by the engagement of the shoulders 28 on thespring-catches 27 with the inner face of the end plate 12. In thisposition the lower or outer end of the slide 37 is against the lower orouter end of the blade-shifter, as indicated in Fig. 4, and the lugs 42on the slide are in line with the notches 43 in the catches 27. Inthisposition, too,the ends 26 of the spring-fingers 25 extend through theopenings 40 in the slide and engage the sides of the knife-blade 14, andthe extreme end edges of these fingers are adjacent the upper edges ofthe openings 40. To project the knife from the handle, the user willpress the iinger-pieces 29 of the catches 27 inwardly between his thumband nger, so that the shoulder 28 thereon will disengage from the endplate 12 and at the same time notches 43 on t e finger-pieces willengage the lug 42 on the slide 37, so that the slide and blade-shifterare locked together. These parts may be then drawn outwardly, and assoon as the ends 26 of the fingers 25 reach the notch 33 on the IOCinner edge of the knife-blade the ends of iingers 25 drop into thenotch, so that when the operating parts are again thrust into the handlethe blade will be projected outwardly into the operative position.(Shown in Figs. 3 and 9.) The rengagement of the shoulders 2S of thesprings 27 with the end plate 12 will securely lock the knife-blade inits rojected position. The spring-catch 44, t at normally holds theknife-blade within the handle, while sufciently strong to preventaccidental displacement of the blade, will yield and be disengaged fromthe notch 45 when the blade is pushed outwardly by the springfingers 25.In the outermost position of the parts, as most clearly shown in Fig. 3,the shoulders or lugs 39 on the clips 21, that shift with theknife-blade, are against the lips or flanges 38 upon the slide 37, butthe lips or flanges 35 are spaced some distance apart from the shouldersor lugs 36 on the clips, so that the blade-shifter whereon the lips 35are mounted may be moved outwardly to a slight extent independently ofthe knifeblade and slide to take up the lost motion between the flanges35 and the lugs or shoulders 36. To return the knife-blade into thehandle, the user will again release the catches 27 by pressing in thefinger-pieces 29, but will not press the latter inwardly a sufficientdistance to engage the notches 43 thereof with the lugs 42 on the slide37. Then by pulling outwardly on the shifter the lost motion be tweenthe lips 35 on the inner end thereof and the lugs 36 on the clips 21will be taken u This slight relative movement between t e blade-shifterand the slide 37 will draw the ends 26 of the spring tongues or fingers25 against the edges of the openings 40 in the slide 37, so that theywill be forced outwardly and out of line with the end of the blade. Thecontinued outward movement of the blade-shifter after the engagement ofthe flanges 35 thereof with the shoulders 36 of the clips 21 will drawthe blade within the handle, as shown in Fig. 10. The springcatches 27may be then pressed together, so that the shoulders 28 thereof willengage the lugs 42 on the slide 37, and-since the ends of thespring-fingers 25 are held out of line with the end of the blade theshifter may be slid into the handle on opposite sides of the blade andback into the position indicated in Fig. S. When the blade-shifter isthrust home into the handle and the catches 27 thereof are again inengagement with the end plate 12 of the handle, the lost motion betweenthe blade-shifter and the slide will be taken up, since the latter isfirst arrested by the engagement of its inner end with the end plate 11of the handle, so that the spring-fingers 25 are released and the partsare in suc position that by pressing the finger-pieces 29 together tolock the shifter and slide together in the released position of thespring-fingers these parts may be quickly drawn out and thrust back intothe handle to project the knifeblade and lock it in projected position.
